How do you know?

I got to thinking about knowing. How do you know? Is it something your heart speaks so eloquently… you just fall? Is it something that speaks to your thoughts, your mind? Is it innate? Does it make you question everything? Do you change your life for it, once you know? Or do you stay the same, pushing the idea slowly into the oblivion? I think you just know. It’s something you cannot fight. You cannot tell yourself it’s wrong, even if you walk away. It’s there. And you just know.
